card went crazy

2004 saturn ion coupe. A few,says prior, battery light started coming on at random. Last night it stayed on, car lost power, battery died. Boosted and right seat belt air bag looking light came on, battery light, check engine light and losing power. Car wouldn't shift out of park to push it and wipers came on by themselves and won't stop till car/ battery dies and no power steering. Please help ideas to check.

Its likely a fault/short in one of the wiring harnesses. Start by
grabbing some electrical cleaner spray and look for any of the
main connectors, they will be large with many 20+ wires near the
engine, press the tab and pull to separate, spray, liberally and
reconnect, see if any improvement. Check your battery cables,
the connectors for rust/contamination and have your alternator
and battery tested. You can look online for locations and colors
of specific wires. If the check engine light is on, have the code
scanned to see why.
